Java中的 YearMonth equals() 方法
Java中 YearMonth 类的 equals() 方法用于比较两个 YearMonth 对象。它将这个 YearMonth 对象与作为参数传递给它的 YearMonth 对象进行比较,并检查两个 YearMonth 实例是否相等。
语法:
public boolean equals(Object otherYearMonth)
参数:此方法接受单个参数otherYearMonth ,它是要与此 YearMonth 进行比较的另一个 YearMonth 实例。
返回值:如果这个 YearMonth 等于 otherYearMonth,则返回 true,否则返回 False。
下面的程序说明了Java中 YearMonth 的 equals() 方法:
程序 1 :
// Program to illustrate the equals() method
import java.util.*;
import java.time.*;
public class GfG {
public static void main(String[] args)
{
// Creates first YearMonth object
YearMonth firstYearMonth = YearMonth.of(2017, 8);
// Creates second YearMonth object
YearMonth secondYearMonth = YearMonth.of(2016, 11);
// check if the two YearMonth instances are equal
System.out.println(firstYearMonth.equals(secondYearMonth));
}
}
输出:
false
方案二:
// Program to illustrate the equals() method
import java.util.*;
import java.time.*;
public class GfG {
public static void main(String[] args)
{
// Creates first YearMonth object
YearMonth firstYearMonth = YearMonth.of(2017, 8);
// Creates second YearMonth object
YearMonth secondYearMonth = YearMonth.of(2017, 8);
// check if the two YearMonth instances are equal
System.out.println(firstYearMonth.equals(secondYearMonth));
}
}
输出:
true
